P82B96PWR

Introduction to P82B96PWR
- P82B96PWR is a dual-bidirectional I2C-bus buffer/level shifter from the P82B96 family. It sits between two I2C buses and translates levels while buffering, enabling devices on different supply voltages or long lines to share an I2C bus.
- How it works: each side has its own supply rail (VCCA and VCCB). SDA and SCL are open-drain on both sides; the chip automatically transfers signals in the proper direction, providing isolation and reducing bus loading.
- Key features: two channels (SDA and SCL), bidirectional level translation, independent supplies, protection against voltage differences, ESD protection. External pull-ups are required on both sides.
- Applications: bridging low- and high-voltage I2C devices, extending I2C over long cables, and isolating sub-systems in mixed-supply designs.
- Quick notes: connect VCCA to the low-voltage side, VCCB to the high-voltage side, wire SDA/SCL across both sides, and add pull-ups on both sides.

Equivalent products (functionally) for P82B96PWR are other I2C bus buffers/repeaters. Closest cross-references:
- TI PCA9517A (I2C bus buffer/repeater)
- NXP P82B96 family (same device lineage across vendors)
Other vendors offer similar I2C buffer/level-shifter parts (e.g., ROHM BD82xx, Renesas uPD series) depending on voltage/pinout. For exact pinout and package, use distributor cross-reference tables (DigiKey/Mouser) or check datasheets.

- Pin count: 8 pins (8-pin package, e.g., SOIC/MSOP).
- Function: Two‑channel bidirectional I2C buffer/repeater and level shifter that connects two I2C buses (SDA/SCL on each side). It buffers and translates levels between the buses, allowing devices on different voltages or at longer distances to communicate.

Manufacturer: NXP Semiconductors.
What kind of company: A Dutch multinational semiconductor company that designs and manufactures integrated circuits and related system solutions for automotive, industrial, and consumer electronics.

P82B96PWR is a dual I2C-bus buffer/level translator. Typical application areas:
- Level shifting between I2C devices at different supplies (e.g., 1.8/3.3V to 5V).
- Buffering/fan-out to extend I2C buses and reduce capacitive loading.
- Isolating noisy or long-distance sections (automotive/industrial wiring).
- Interfacing remote sensors, actuators, or MCU peripherals across cables or between PCBs.
- Safe operation in mixed-voltage, multi-drop I2C/SMBus environments.
